Scope of Communications for the Personalized Space

Personal Space

  • Term “Personal Space”

    • Originated from social psychology

      • The region surrounding a person which they regard as psychologically theirs.

    • The notion of personal space comes from Edward T. Hall “The Hidden Dimension (1966)”,

      • Intimate space < 1.5 feet

      • Personal space < 4 feet

      • Social space < 12 feet

      • Public space < 25 feet

    • Invasion of personal space often leads

      to discomfort, anger, or anxiety

    • Personal space is also affected by a person's

      position in society with more affluent individuals demanding a larger personal space

Personalized Space

  • Personalization involves using technology to accommodate the differences between individuals.

    • Personalization implies that the changes are based on implicit data.

    • eliminate repetitive tasks; recognize habits and shorten the path to engage in such habits

    • provide more specific information that is increasingly relevant to a person’s interests; replace “average” information with information specific to that person’s environment

    • provide one-stop services; accommodate unique personal preferences

Requirements for the Personalized Space

  • Personalization of space

    • Make public space react differently between individuals based on implicit data

    • Feel the space within reach of any limb of an individual.

  • Public space into personal space

    • Exchange implicit data and explicit control among human & things in the public space of an individual

    • Profile based, behavior based, collaboration based

  • Requirements of communication for personalized space

    • Group based communication in public space

    • Number of communicators in public space will increase dramatically

    • Guarantee the various quality of service at once




Public Space & Personalized Space


Specification of the Personalized Space

  • Radius of public space which will be converted personal space

    • Sphere with 25 feet radius

  • Number of communicators involving a collaboration for the personalized space

    • Gradually increasing from 3~4 to 60~80, or even more ?

  • Communication type

    • peer-to-peer, 1-n, n-1

    • n-m group-cast (group-chat)

  • Traffic characteristics

    • delay tolerant data, real-time control, audio/video stream


Architectural View of the Personalized Space

  • Independent personal space

    • Communicators in public space are involving to collaborate with no need of supporting from outside of the public space

    • Communications within public space

  • Inter-related personal space

    • Space is inter-related with the pre-defined spaces

    • Information for collaboration needs to be provided from outside of the public space

    • Communication to outside of the public space

  • Chased personal space

    • Personalized spaces are following to an individual

    • Communication between consecutive public spaces







Inter-related Space

Chased Space


Communication for the Personalized Space

  • Public space communication

    • n-m groupcast

    • at least 25 feet range

    • nx10 bps ~ m Mbps throughput

    • ms ~ min latency

  • Area access communication

    • Getting to database through core network

    • Wired or wireless network

  • Space chasing communication

    • interonnection between public spaces

    • nx10 bps ~ m Mbps throughput

    • ms ~ min latency


Candidate Technologies for the PSC

  • Public space communication

    • Bluetooth

    • ZigBee

    • UWB

  • Area access communication

    • Cable Network, Telephone Network

    • WiFi

    • Cellular Network

  • Space chasing communication

    • Interconnected through area access network

    • Hand-over between public spaces


Scope of the PSC project

  • Public space communication

    • n-m groupchat, nx10 bps ~ m Mbps, ms ~ min

    • One fits for all

    • MAC only

    • Need new PHY & MAC

  • Area access communication

    • Use as it is

  • Space chasing communication

    • Hand-over between public spaces

    • Managed on MAC layer
